In a nutshell, it is used instead of a S-AFC. It is not a reflach of your ECU. It is a seperate box custom made by CN's techies. It is a piggyback in the exact same fashion as the S-AFC is in that is adjusts fuel based on the stock ECU's fuel map.
Imagine if they made a S-AFC III... And it was capable of reading tempature, a/f ratio, knock, and other things already monitored by the ECU and change the fuel adjustment ON THE FLY just like an AFC can, but automated by computer instead of by hand.
This box will be "adjustable" in general by hooking up a laptop to your car for basic setup like telling it what PSI you are running so if can plug in safe/rich values for the first time you start the car and program itself as you drive from then on out.
There is also a good chance their will be two versions of this computer - one that has the added feature of RedLine increase.
Expected release is sometime between April and December of '04
... Guess it pays to be an existing customer. :D
Oh, that reminds me. I was told it would cost me $300-$500 to purchace JUST the guardian box to install on my car so I can rip out the AFC. I am GUESSING that means like $300 for standard box and $500 for the one with the redline increase - but that is just me guessing. I make that assumption only because anything CN ever quoted me for in the past while in development they released for the quoted price or less, so giving me a range and knowing their may be 2 versions makes me believe this.
Will let you all know if I find out any more.
